NICE Plane!

Great plane! Also great flying and landing! That's a fast little bugger!
-
That looks big and expensive, I wouldn't trust myself 10 feet near it lol.

That must be quite the mother to fly
-
That is pretty cool, I don't think I will go higher than foamies myself.
-
That has to be one of the coolest jet R/C I've ever seen. That jet would be cool to put in one of those cameras that you can watch as you fly it, that way you could take it up high and far.
-
I was looking around YouTube after watching that video and came across this, with out a doubt the largest R/C jet I've ever seen, this thing is just huge, you could almost fit some small kids in it for a ride, and I can't believe how maneuverable it is for it's size.
Extremely large C-17 R/C

Here's another extremely large R/C, it claims to be the worlds largest, it's a B-29, something like this one has to be really expensive, anyone got an idea on how much it would be?

I have to ask, is that a turbine engine it has?
B-29 really neat, but can the size beat this one.

Well thats the same video that I just posted, it's the link just above the B-29 one, and yeah the B-29 one is definitely bigger then the C-17, at least the wingspan is bigger on the B-29, the C-17 might have a taller tail.
As for the plane in the pic I don't know, it's a close call, but if that one was bigger it isn't anymore obviously. :D

"This 1/9th scale radio-controlled C-17 model was built in the United Kingdom. To date it has about 20 flights. It was built as the centerpiece of a 15 program television series produced in the U.K. for the Home and Leisure satellite TV channel.
Built with the aid of three friends, it took 1 year to build and is powered with 4 Jetcat P-120 turbines with a total thrust of 108 lbs. The models weighs over 250 lbs fuelled, and carries 12.5 liters (3.3 US gallons) of 95% kerosene and 5% turbine oil fuel.
Other details include 5 Futaba PCM receivers, 16 battery packs (93 cells), 20 Futaba servos, on board air compressor, electro/pneumatic retracts, etc.
The four builders are shown in the lower left image above. Colin Straus is at the nose of the aircraft.
Wingspan is 20 feet 8 inches, and the top of the fin is 74 inches (6 feet 2 inches) above the ground.
Takeoff weight is 264 lbs.
The rear cargo doors open and they drop an r/c jeep on a pallet, as well as 2 freefall r/c parachutists. The model also has smoke systems both of the inboard turbines, and uses 2.4 GHz data link to provide real-time data to a laptop computer on the ground while in flight, this data includes airspeed, turbine RPM, EGT, fuel consumption, etc. It is covered in fiberglass and epoxy resin.
Built mainly from balsa and ply, with many glass and carbon fiber moldings to reduce weight. This C-17 Globemaster III is one of the largest jet models in the world today! Complete with retractable landing gear and pneumatically operated flaps"

WOW! I can not image how much it cost. So, they do used turbine engine. that is interesting.

yes actual jet engines.

Flying shark!

Yes, some RC jets use electric powered fans, some use actual turbines...
I have 1 turbine, and several electric birds
The funny thing is, once youg et above the smaller size electric stuff, to go electric costs almost the same amount as to do a turbine... and the tubine has SO much more "cool factor"
I have around 6 smaller 45" and smaller wingspan electric jets, which are fun to fly for sure, but my Turbine F/A-18 is amazing... and also I feel a tug on my wallet every time I fly it though lol...
Crash that baby and im out close to 15 grand...
Turbines tend to burn upon crashing, just like the real thing... and usually nothing is left that can be salvaged...

Ok, i do not know much in this area. When did these real turbines come out in the market? What is the biggest size, once again excuse my arrogance on this, or biggest thrust can you get? 15 grand, wow!
-
Not sure what the ultimate in thrust is, In my case I use one of these:
http://www.jetcatusa.com/p200.html (http://www.jetcatusa.com/p200.html)
Buy your own P-200 here:
http://www.sitewavesstores5.com/mm5/merchant.mvc?Screen=PROD&Store_Code=JetCat&Product_Code=P200-SX&Category_Code= (http://www.sitewavesstores5.com/mm5/merchant.mvc?Screen=PROD&Store_Code=JetCat&Product_Code=P200-SX&Category_Code=)
The JetCat P-200-SX, has 52lb of thrust at 112,000RPM..
I fly my F/A-18 which weighs about 49 lbs fuelled on that plane, which gives me a grater than 1:1 T/W ratio which is FUN! :joystick:
So far as I know this is the most powerful commercially available turbine for hobby use.. there may be something with more thrust, that I am not aware of, and it is very likely newer more powerful stuff is in development...

WOW! That is something. i am sure they will get bigger and bigger to a point that we will see people flying on the big R/C. I hope it is worth the money, a bit to much for me for i will most likely crash them on the first take off.
Oh, do you have insurance on them?

the only insurance is that you ensure your thumbs are up to the task of flying it!

LOL, yea with 5 grand on you butt, i would ensure that.

Looks to me like the ground came out unscathed, at least...

I've been flying RC for over 30 years, my latest build is a B25, heres a video of the exact plane im building

Well, looks like 10 grand up in flames.

Should that guy be smoking over the Sr71 while they fuel and start it?

hmmm i was just planning on ordering C-123K plans that were 1/6th scale. That would give it a 18.33ft wingspan, length of 12.7ft length and 5.6ft height but hell, i might as well just go up to 1/3.66th scale which gives me a 30.05ft wingspan, 20.83ft length and 9.28ft height. That would be bigger than that b-29. The advantage i have is i have a real c-123K to use for all my references of detail in addition to the plans at my fingertips since i work at a museum that has one and i only live 2min away from the airport. My goal for it would be to get it built take it on a few airshow (both real planes and RC) circuits and then donate it to the museum. I want to detail it just as our real one is though so it will look like this:
(http://i225.photobucket.com/albums/dd320/flightsimer/airplanes/DSC01115.jpg)
I havent decided on what construction im gonna do. Most likely wood, though i do like the idea of it being composite, but i think thats just out of my reach with its size.
completion time 1-5years lol

The most astonishing part of that whole video is that the old boy's *wife* actually appears to be out there helping him with his giant toy plane.
In which Teutonic paradise are such fabulous creatures to be found?
-
i found the video of the B52 crash. I actually wasnt even looking for it, but instead was reading on a site about giant scale planes.
http://www.hooked-on-rc-airplanes.com/giant-scale-rc-airplanes.html
ive actually seen the video before without realizing that it was the one mentioned above...

Typical turbines cost around the price range of $2-5000. Then you have to add the recivers wich in that case they prolly have around 5 or 6, $180. Two or more transmitters, $300, and I can go on and on but that model can go for about the cost of a pourche.

I'm suprised nobady has posted this one. Onl thing missing is a nuke :noid
